Which step is the first mistake made? Find three consecutive odd integers whose sum is -45.
Step 1: x + (x + 1) + (x + 2) = =45
Step 2: 3x + 3 = 45
Step 3: 3x = 42
Step 4: x = 14
Step 5: The integers are 14, 15 and 16.

answer: i don't understand. what are the options

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

answer: the answer to this problem is 2x and 2-x both have x as well as 2

step-by-step explanation: first you have to see what is the closest thing they have similar second you note it example 4x and 4+x they both have x and 4
